Preparation and microstructure of titanate nanowire thin films by spray Layer-by-Layer assembly method

Nanostructured thin films made by dewetting method of layer-by-layer assembly.

Layer-by-layer (LBL) assembly is one of the most ubiquitous coating techniques today. It also offers a pathway for multifunctional/multicomponent materials with molecular-scale control of stratified structures. However, technological applications of LBL are impeded by laborious and fluid-demanding nature of the process. While vertical organization of LBL films is natural for this technique, the...

Preparation and characterization of polymeric thin films containing gold nanoshells via electrostatic layer-by-layer self-assembly

Mechanical Properties and Microstructural Evolution of Ta/TaNx Double Layer Thin Films Deposited by Magnetron Sputtering

Crystalline tantalum thin films of about 500nm thickness were deposited on AISI 316L stainless steel substrate using magnetron sputtering. To investigate the nano-mechanical properties of tantalum films, deposition was performed at two temperatures (25°C and 200°C) on TaNx intermediate layer with different N2/Ar flow rate ratio from 0 to 30%. Nano-indentation was performed to obtain the mechani...

Layer-by-layer epitaxial thin films of the pyrochlore Tb2Ti2O7.

Layer-by-layer epitaxial growth of the pyrochlore magnet Tb2Ti2O7 on the isostructural substrate Y2Ti2O7 results in high-quality single crystal films of up to 60 nm thickness. Substrate-induced strain is shown to act as a strong and controlled perturbation to the exotic magnetism of Tb2Ti2O7, opening up the general prospect of strain-engineering the diverse magnetic and electrical properties of...

Deposition and characterization of SnO2:Sb thin films fabricated by the spray pyrolysis method

In this study, thin films of transparent semiconductor tin oxide doped with antimony impurities on the glass substrates with different concentrations of antimony that have been prepared using spray pyrolysis method. The effects of different concentration of antimony on the structural, optical, and electrical properties of the thin films were investigated. Prepared layers were characterized by X...
